nav seems to only collect cam records from a random subset of ports on each switch.
We're tried snmpwalking the switch, and it seems like the mac addresses are reported correctly by the switch.
This occurs both on nxos (Nexus) switches and older IOS switches
There is likely nothing random about it. Accessing forwarding tables on Cisco devices is quite awkward, since Cisco ignores the Q-BRIDGE-MIB - which may be related to your issue (but I suppose you are accounting for community indexing when snmpwalking?).
I'd suggest addding "nav.ipdevpoll.plugins.cam = DEBUG" to NAV's `logging.conf` and then restarting ipdevpoll to see what this plugin logs during the execution of topo jobs.
